Special Counsel Robert Mueller’s office wants to ask President Donald Trump about obstruction of justice, sources close to the White House tell ABC News. According to sources, the president learned within the last day that the special counsel will limit the scope of questioning and would like to ask questions both orally and written for the President to respond to.

According to sources familiar with the President’s reaction Wednesday morning, that was the genesis for his early morning tweet storm. Trump took to twitter in one of his strongest attacks against the federal probe into Russian meddling in the 2016 election, saying: “This is a terrible situation and Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further. Bob Mueller is totally conflicted, and his 17 Angry Democrats that are doing his dirty work are a disgrace to USA!”
